IMPROVEMENT m PRESSER-FEET FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 1 33,411, datedNovember 26, 1872.

forming part of this specification, in which.

drawin g- Figure 1 represents a side view of this invention. Fig. 2 is aplan or top view of the. same, showing the presser-foot in two differentpositions. Fig. 3 is a transverse section of the same.

Similar letters indicate corresponding parts.

This invention consists of a presser foot which is provided with twothroats located on the same side of the foot, and which is connected toits shank or support so that either of the throats can be brought inworking position, and that the pressure exerted by the foot on thematerial to be sewed can be brought on eithenside of the needle. Thebottom surface of the shank is made inclined, so that the back of thefoot is elevated from the material. I

In the .drawing, the letters A A designate our presser-foot, which issecured to the shank B, and extends beyond said shank in two directions,each of the branches A and A of said foot being provided with a throat,a or a. (See Fig. 2.) The connection between the footA A and the shankBis effected by means of a pivot, b, (see Fig. 3,) so that said foot canbe turned round, and a button, 0, is provided which serves to lock thefoot in either of the positions shown inFig. 2. The bottom surfacef ofthe shank B is inclined, (see Fig. 1,) for the purpose of throwing thetail end of the presser-foot, or that branch of the same which is not inworking position, clear of the work.

The advantage of our invention will be readily understood by referringto Fig. 2 of the drawing. If a fold, O, is to be sewed down upon theskirt of a dress the branchA of the presser-foot is brought to bear uponsaid fold and one edge thereof is sewed on. But if the foot A is movedto the opposite edge its pressure is brought chiefly upon the body ofthe skirt, and it is very difficult to keep the fold in the properposition.

With an ordinary presserfoot, therefore,- the operation of sewing on thesecond edge of the fold can only be performed successfully by reversingthe skirtan operation which takes much time, and which is difficult toperform on account of the formation of the skirt. With our presser-footthe operation of attaching a fold to the skirt of a dress can be easilyaccomplished; After one edge of the fold has been sewed down thepresser-foot is reversed, and the branch A is brought in operation. Thepressure of the foot is thereby brought on the opposite sideof theneedle, and the second edge of the fold can be sewed down simply bysliding the material in or out on the cloth-plate of the sewing-machine.

In the above we have given one example of the work to be produced by ourpressercal operators of sewing-machines.

What we claim as ne'w, and desire to secure by Letters Patent, is-- 1.The compound presser-foot, provided with two throats, located on thesame side of the foot, so that by simply reversing the position of thefoot it will press on either side of the needle, substantially asdescribed.

2. The compound presser-foot, with two branches, A A, and two throats onthe same side thereof, secured to a shank provided with an incline, a,at its lower end, substantially as described, so that on reversing thefoot its back end will be elevated from the work.

This specification signed by us this 11th day of October, 1872.
